A kind of river ecological flexible slope protection structure and construction method

Abstract

The invention discloses a riverway ecological flexible slope protection structure and a construction method. The slope protection structure comprises stone and slope clustering ropes, one end of eachslope clustering rope is fixedly connected to the levee crown of a river levee, the other end of each slope clustering rope extend to the river bottom along the slope of the river levee, the slope clustering ropes are sequentially in the flowing direction of a riverway and penetrate the stone to cluster the stone to the slopes. The riverway ecological flexible slope protection structure has the high structural integrity, adaptability and water permeable capacity and the good flood control and flushing preventing effect, is easy and quick to construct and low in cost, does not influence plant growth and can beautify the environment and keep ecological, and stone gaps can be directly filled with natural soil.

Description

technical field [0001] The invention relates to the technical field of water conservancy project river improvement, in particular to an ecologically flexible slope protection structure of a river and a construction method. Background technique [0002] In the river management of water conservancy projects, in order to prevent the slope or riverbed from being scoured by water flow, various paving or planting are done on the slope surface and slope foot of the embankment slope to ensure the safety of the river embankment. The existing slope protection technology can be divided into Planting slope protection, gabion slope protection, masonry slope protection and laying concrete prefabricated block slope protection for lattice beams in different areas. With the development of ecological civilization construction and combined with engineering practice, the above slope protection technologies generally have the following problems: [0003] 1. In order to maintain the ecological ba...

AI Technical Summary

Problems solved by technology

[0003] 1. In order to maintain the ecological balance and beautify the environment after slope protection, artificial planting or high-tech materials such as ecological concrete are used, which greatly increases the project investment cost. At the same time, ecological concrete has relatively high requirements on the region, climate and flow rate, and the later maintenance costs are high.

[0004] 2. Most of the materials used are concrete and masonry, which have a large self-weight and require a large foundation bearing capacity for the slope protection slope

Concrete is an artificial material, which will have a great impact on the living and growing environment of aquatic animals and plants. Concrete embankments or slope protection will isolate the entire aquatic ecological environment from the outside world, which is not conducive to ecological protection.

[0005] 3. The water permeability of the material is poor, and the groundwater and permeable water cannot be infiltrated from the structural rockfill gaps in a timely manner, resulting in the rise of the groundwater level, thereby increasing the groundwater pressure under the slope and affecting the stability of the embankment

[0006] 4. Most slope protection structures are rigid structures, which cannot adapt to foundation settlement. The structural integrity is poor, and they are easy to crack and damage, which in turn increases maintenance costs.
